Include architecture-specific header file first and then define

Browse source 
various other types and constants based on it.
(unw_error_t): A UNW_EINVAL, UNW_EBADVERSION, and UNW_ENOINFO.
(unw_frame_regnum_t): Instead of hardcoding the numbers for the
	well-known frame registers, use the architecture-specific
	(target-dependent) values instead.
